To all t0/om may 'concern v Be it known that l, JoiiN E. Sain), a citizen of the United States, residing` at George, in the county of Lyon. and'State olowa, have invented certain new and useful linproveinentsin lVriting-Tablets; and l do hereby, declare the following to be a full, clear, and exact'desjcription vot the invention7 such as AWill enable others skilled in the art to which it appertains to niake'and use f rlhis invention coinprehends improvements in Writingl tablets and relates more particularly to 'those of the continuons type' wherein a strip of paper is nnwonnd from one spool and wound .upon another.

The primary object of the invention re-V sides in the' provision ot a writing or figuring tablet of this nature which will be of use by cashiers, paying tellers, and boolleepers,

`but which may also be foundrusetul by persons employed in other,4 avays who inay have occasion-to do considerable figuring.

Another object of the invention isr to pro-` vide -a device of this nature which Ywill hold the exposed portion'of lthe paper practically on a level with the supporting surface which 4 may -be a desk, table, or counter, and which niay' be easily operated so as to feed the paper,ivhereby afresh surface is exposed for Writing or figuring. l

Another and niore specic obJect of theinvention is to provide anoveltorni ot brake or stop device for the rolls ot paper. t

lViththe'se and other obJectsin vien', 'as

'will become more apparent as the description proceeds, the invention consists in Veertain novel features of construction, coinbina' tion, .and arrangement of parte,l as will be hereinafter described and claimed. Y Y For a complete understanding of iny ini vention, reference is to be had to the tolloiving description. and accompanying 'drav-Jings,

in Which,

Figure l is a top plan vienT of iny device showing the saine attached to a supporting surface, Fig. is a side elevation with. 'the supporting surface shown in sect-ion, Fig. 3 is abottoni plan ,View of the device, F ig. is a transverse section, parts oi trie niaclii'ne being shown in elevation,I and, Fig. 5 is a del tail side elevation'ot one of the brake or tension plates. c i.

n rlefeiring in detail to vthe drawings by numerals, l designates a suitable support, suoli as a desk, table, or counter, 1vhicli in opening 2 and is somewhat larger Vthan the opening, extending` beyond the vside edges of the saine over -the top of the supporting surface. Theend portions of the plateare bentdownivarclly into the opening, as indicated by the numeral l, andt'orin bearing surfacestor the paper, to be describ'eif late-r. Depending lugs 5 are formed-adjacent 'tlf' corners of the base plate for reception i in openings'forrned in the suppe lting tace so as to. hold the plate in it. proper@ sition. The plate is Aalso formed adjacent one end with paper guides ti, which engage the edges of the paper strip,.as it is moving over the plate.

A pair of -U-sliaped trames, generally designated V7 and'fo and 'having the depending arins 9, are secured to the under side of the base plate-3, for the purpose of supportingthe spoolslO and l1. The spoollO 'revolves lfreely about the shaft l2, Whereas the spool ll is lined to and movable with the shaft 1 3. This last'in'eiitioned-sliait has' rigidi",7 (secured to `one end a bevel gear ll, which meshes with a similar gear l5 seeuredto the lower end ofa vertical lshaft 16. The

shaft 16 extends through a bearing l? sc-l oured to one of thel arms 9 of the traine 8 and also through an openinf formed Vin the -base plate 8. A crank han Ale l is-secured to the'npper end of the shaft 16 so that the latter may be easily rotated so as to wind the 4paper 19 troni 'the spool l0 onto the spool ll. is is clearly shown in the drawings, the paper passes troni the spool v10 over tlienp surface 'of the base plate, between the gui les 6,' and down ander the base plat-e to the spool ll.

ln order to, prevent the spools rotating too rapidly, l provide' the teiisioiior brake plates 20. These plates are preferably 'formed or' sheet metal and have their lower extremities enlarged and curved tovard eachI other, indicated by the numeral' A pair oit sleeves 22 is formed upon the upper edge oi" one of the plates and a sleeve Q3 is formed upon the upper edge of the other plate, for reception within the sleeves 2% A pintle or iivot rod @l extends through the sleeves `and is securedat its ends within the ears ltorinedon the underside of the plate 3. A curved red 26 having enlargements El? y:formed npon its extremities, extends through .openings formedin the plates and the VeX- y pansive spiral spring 28 surrounds that porland as one tion of said rod which extends between the plates. The spring forces-the plates against thepaperrolled uponl the spools 10 and 11 paper roll increases in size while the other diminishes, the plates swing about the pintle 24 as a pivot. To place the ma? 10 ,the frame 7 and one en chine in proper'running order the spool 10 carrying a full roll of fpaper isl .placed in 0f the paper car` ried over the outer surfacefof the base plate figures or writing the shaft 16 is rotated'so'- and attached to the spool 11. Then as the exposed surface of the'paper is covered with as to cause-the paper to wind upon the spool -11, whereby `a fresh surface is exposed.

l/Vhen the spool 11, the shaft 16 is raised so as to carry-l the gear 15 above the gear 14 and then after the cotter pin 29 has been removed the'shaft $3 may be withdrawn from the frame 8 in order to detachA the spool 11. After this has.

neen dene, the empty spool 10 is transferred to `tbe'lposition primarily occupied by the spool 11 and a fresh roll of paper placed in the frame-i7.' If it is desired to review soine of the figures or writing upon'the paper backwardly strip, said strip may be grasped and pulled so as to unwind the paper from the spool 11. l

From ,the foregoing-description taken in connection with the accompanying drawings, it, will be apparent that I have provided an extremely simple figuring or to another, whereby writing tablet which may be conveniently secured to a. suitable surface so as not to be paper is entirely wound upon the shown and described fthe preferred embodinfient of my invention, Ido not wish -to be limited to this exact construction, combina-- tion, and arrangementof partsbut may make such changes las' will fall Within the spirit and scope of the invention as claimed.

1. In a device of the'characterl described, a base plate, a pair of paper rolls, means for winding the paper from one roll tothe other,l

and a brake comprising la pair of brake plates pivotally secured at their upper ends to the base plate fand projecting between the paper rolls, a curved rod extending through opei'iings formed in the plates and having its center ofl curvature at the'pivot point ofl the brake plates, and an expansive spiral spring surrounding that portion of the rod included between the plates, whereby said plates are forced againsttlie rolls..

'2. The combination with a supporting surface having an opening foiniedtherein, of a base plate positioned over said opening and resting lupon -the supporting surface,

said base plate being formed with dependvinglugs engaging with the supporting surface, spools supported under said plate, means for winding paper from one spool to the other, .the'paper passing over the top of. I

lthe plate, a .pair of ears formed upon the under side of the plate between the spools, a pivoted rod supported by said ears, a pair of brake plates connected to said pivot rod, l

and means for forcing the platesv against the spools. 1 y
